Embodiment Construction
[0112] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0113] The fault detection of the display panel is usually carried out by means of a fault detection system. The fault detection system includes: a fault detection device, a driving module and an image acquisition module, and the fault detection device is electrically connected with the driving module and the image acquisition module. When performing fault detection on the display panel based on the fault detection method in the related art, the current image acquisition module cannot support the fault detection on the display panel with higher resolution.
[0114] For example, assuming that the field of view of the image acquisition module is consistent with the effective display area of the display panel, the resolution of the image a...

The application discloses a fault detection method, device system and storage medium of a display panel, belonging to the field of display technology. The method includes: driving a plurality of sub-pixel groups of the display panel to emit light sequentially; when each sub-pixel group emits light, collecting a bright state image of a target area in the display panel through an image acquisition module; The brightness of the pixel to which each sub-pixel belongs in a sub-pixel group is taken as the brightness of each sub-pixel; whether the sub-pixel of the display panel includes an abnormal point of brightness is determined according to the brightness of the sub-pixel in the display panel, and the abnormal point of brightness includes at least one of a bright point and a dark point. . This application solves the problem that the current image acquisition module cannot support the fault detection of higher-resolution display panels. Based on the fault detection method provided by this application, it can perform fault detection on higher-resolution display panels. This application Used for fault detection of display panels.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a fault detection method, device system and storage medium for a display panel. Background technique [0002] With the development of science and technology, more and more display panels are used in people's production and life. After the display panel is manufactured, it is usually necessary to perform fault detection on the display panel to determine whether the sub-pixels of the display panel include bright spots and dark spots. The bright spot and the dark spot are both faulty sub-pixels, and the brightness of the light emitted by the bright spot is much greater than that of the surrounding sub-pixels, and the brightness of the light emitted by the dark spot is much smaller than that of the surrounding sub-pixels. [0003] In the related art, a fault detection system is used to perform fault detection on the display panel. The fault detection system includes...
